If like me, you are always playing almost perfectly, and yet, seems to find no way out of 4-5 wins in Arenas, rejoy!!! I may have found the reason!!!
It is becomming more clear and clear everydays, after spectating my legendary friends constantly and can't not miss to notice that I play exactly like them, I build my decks exactly like them... BUT, I do not face the same opponents and the game does not give me the same cards choices
What I become to suspect is that the server will create a list of every persons that buys arena entrys.
Once your account has been flaggued as a "regular" arena entry buyers, I suspect the servers gives you bad luck and a low ammount of rares, legendaries and epic in your arena deck creations. Also makes you face opponents with awesome synergies. Everything to make you lose and buy another entry and never self suffices. It has become very apparent in the last days. Now that I mention it to you, please try to notice it as well, I'm sure you will.
Everything here would be within the norms of the US Full Spectrum Dominance doctrine.
